This is coming from a position of not having been tested nor even  
thought through properly, but how about:

#define _NSANIMATION_LOCK \
{ BOOL __gs_isLocked = NO; \
//... \
}

?  That should remove the C99-esque behaviour - I don't _think_ it  
makes the macro any less usable than it already was but as I say, I  
haven't studied its use much.
